This externally-mounted dot sight is perfect for super-telephoto photography of wild birds. This accessory assists in framing when photographing far-away subjects. The brightness and position of the reticle can be adjusted. Because it is powered by a coin-type battery, it can be used when attached to the hot shoe or cold shoe.
